无法使用MP1开发板上的NFS

zhildren

开发板已经接上网络，可以ping通百度。

1. debian@lubancat123:~$<font color="Red"> ping www.baidu.com</font>

但安装NFS始终无法成功。
照着别人的解决办法，先sudo apt update再sudo apt upgrade后提示如下。

我也遇到了一模一样的问题，updata结果都是一样的

发现很多人都遇到了这个问题，野火的资料里面也没有提醒，论坛里的人乱支招。

先用SD卡刷Debian镜像系统才有apt等命令。

我也是这个问题

有解决办法吗

搞了两天了，现在是开发板能ping通主机能ping通百度不能ping通虚拟机，Ubuntu能ping通百度不能ping通开发板和主机，开发板与主机没有网线连接，搜了好多方法都是得网线连接，人麻了

优秀sys

我解决了，烧写最新的debian镜像，用sd卡烧写，然后fire-config来把sd卡镜像烧到emmc中，用32programm烧写不了qt的镜像，所以推荐用sdk。烧写完之后就可以update了安装nfs也可以了，还有一个坑找了半天nfs的服务器ip地址就是虚拟机的IP地址，我还以为是路由器的网上找了半天，ifconfig就可以找到。
